AAMAS '11: Proceedings of the 10th international joint conference on Autonomous agents and multiagent systems, Taipei (Taiwan) (2011)Abstract:
Virtual Institutions (VIs) have proven to be adequate to engineer applications where participants can be humans and software agents. VIs combine Electronic Institutions (EIs) and 3D Virtual Worlds. Electronic Institutions are used to establish the regulations that structure interactions and support software agent participation, while Virtual Worlds facilitate human participation. In this paper we propose Virtual Institution eXEcution Environment (VIXEE) as an innovative communication infrastructure for VIs. Main features of the infrastructure are i) the causal connection between Virtual Worlds and Electronic Institutions, ii) the automatic generation and update of the VIs' 3D visualization and iii) the simultaneous participation of users from different virtual world platforms. We illustrate the use of VIXEE system in a simple eAuction house example.

Conventions; Social Networks; Self-organizationAbstract:
We present the notion of Social Instruments as mechanisms that facilitate the emergence of conventions from repeated interactions between members of a society. Specifically, we focus on two social instruments: rewiring and observation. Our main goal is to provide agents with tools that allow them to leverage their social network of interactions when effectively addressing coordination and learning problems, paying special attention to dissolving meta-stable subconventions. Initial experiments throw some light on how Self-Reinforcing Substructures (SRS) in the network prevent full convergence, resulting in reduced convergence rates. The use of an effective composed social instrument (observation + rewiring) allow agents to eliminate the subconventions that otherwise remained meta-stable.
Generating 3D Virtual Environments Using The Virtual World Builder Toolkit

CGI 2010, Singapore (2010)Abstract:
Hybrid systems such as those that combine 3D virtual worlds and organization based multiagent systems add new visual and communication features for multi-user applications. In this paper we present a tool called Virtual World Builder Toolkit (VWBT) that can automatically generate a 3D virtual worlds (VW) from an organization based multiagent system (MAS) specification that establishes the activities participants can engage on. This tool provides a comfortable defini- tion and execution of Virtual World Grammars (VWG) which are an extension of shape grammars to support the generation of virtual world designs.
Building Quests for Online Games with Virtual Institutions

Workshop on Agents for Games and Simulations at AAMAS 2010, Toronto, Canada, p.125-139 (2010)Abstract:
This document describes how to re-purpose an existing agent technology called Virtual Institutions as a mechanism to define new “quest” elements in Massively Multiplayer Online Games based on Multi-Agent Systems. Quests are a very important part of most Massive Online Games as they wield to flow and narrative of the game in a linear or nonlinear manner.

Hybrid systems such as those that combine 3D virtual worlds and organization based multiagent systems add new visual and communication features for multiuser applications. The design of such hybrid and dynamic systems is a challenging task. In this paper, we propose a system that can automatically generate a 3D virtual world (VW) from an organization based multiagent system (MAS) specification that establishes the activities participants can engage on. Both shape grammar and virtual world paradigms inspired us to propose a Virtual World Grammar (VWG) to support the generation process of a virtual world design. A VWG includes semantic information about both MAS specification and shape grammar elements. This information, along with heuristics and validations, guides the VW generation producing functional designs. To support the definition and execution of a Virtual World Grammar, we have developed a so named Virtual World Builder Toolkit (VWBT). We illustrate this process by generating a 3D visualization of a virtual institution from its specification.
